T0 @ZZ wtmn it mln/y 0071/067711:

Be it known that we, EDWARD H. EARN- sHAw and WTILLIAM H. GARTLEY,citizens of the United States, residing at the city of Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have jointlyinvented certain new and useful Improvements in Apparatus for Making'Gas, of which the following is a specification.

The invention relates to improvements in that class of gas apparatus inwhich use is made of retorts and of recuperator means for b heatingthem; and the principal object of the invention is to provide forindependently controlling the temperature to which the retorts areheated at different portions or sections of their lengths.

To this and other ends hereinafter set forth the invention, stated ingeneral terms, comprises the combination, with a bench of retorts andits secondary air-supply, of means for introducing' more or less air inthis secondary air-supply at different sections throughout the lengthsof the retorts.

The invention further comprises the `improvements hereinafter describedand claimed.

The nature, characteristic features, and scope of our invention will bemore fully understood from the follow-ing' description, taken inconnection with the accompanying drawings, forming part hereof, inwhich- Figure l is a perspective view, principally in section,illustrating portions of a gas-retort apparatus embodying features ofthe invention. Fig. 2 is a view showing at the lefthand sidethereofafront elevation and at the right-hand side a sectional view ofapparatus embodying features of the invention, -and Fig. 3 is asectional View taken on the line 3 3 of Fig. 2 on an enlarged scale.

In the drawings, Fig. 2, 1 represents the retorts.

2 represents the passages for feeding gas which is burned by thesecondary air-supply at 3 in order to heat the retorts. rIhe products ofthis combustion traverse the fiues 4.

are horizontal, as is shown in Fig. -1 and also in Fig. 2. The passages6 for the incoming secondary air-supply are arranged side by side, asshown in Fig. l, and vertically. The arrows in that figure marked 8"show the path of the products of combustion and the arrows marked 9 showthe path of the secondary air-supply in one of the passages, of whichthere are shown six, althoughthe number is not material nor is theconstruction and arrangement of details of the flues and passages. Theintake for the supply of secondary air is subdivided, each portion of itprovided with a door or other means for regulating the passage of airthrough it. Each subdivision extends to a set of passages 6. As shown inthe drawings, there are two subdivisions l() and ll. The subdivision l0is arranged-to supply air to the three separate vertical passages 6,which are located nearest the front of the apparatus, and thesubdivision ll is arranged to supply the group of three passages 6. nearthe back of the apparatus. Of course the number of subdivisions, as wellas the number of passages connected therewith, may be increased ordiminished.

The mode of operation of the described improvement may be explained asfollows: The apparatus as a whole is operated in the ordinary way, withlthe exception that the doors, as 13 and 14:, which control the intaketo the secondary air supply, are so opened and closed as to control thedegree of heating of the various portions of the retorts throughouttheir lengths, and in this way the operation of the apparatus as a wholeis materially improved. For example, it frequently happens that theretorts are not charged evenly throughout their lengths, and by thepresent invention this may be corrected by the application oi' theproper degree of heat in proportion to the extent ot' the chargingthroughout the length ot' the retorts.

It will be obvious to those skilled in the art to which our inventionappertains -that modifications may be made in detail without departingfrom the spirit thereof. Hence we do not limit our invention to theprecise construction and arrangement of parts hereinabove set forth, andillustrated in the accompanying drawings; but,

Having thus described the nature and objects ot' our invention, what weclaim as new, and desire to secure by Letters Patent, is# l. Arecuperative gas-retort setting provided with retorts, a gas-furnacehaving gasoutlets arranged beneath the retorts, eductionlues forcarrying off the products of combustion, separate systems ofinduction-fines surrounding` the eduction-liues and heated thereby andarranged to separately discharge in proximity with said gas-outlets, andmeans at the points oi' admission for controlling the intake of air toeach system of inductionflues thereby providing independent secondaryair-supplies for dilerent portions of the setting throughout its length,substantially as described.

2. A recuperative gas-retort setting' provided with retorts, agas-furnace having gasoutlets arranged in rows beneath the retorts, eduction-liues for carrying oli' the products of combustion, separatesystems of inductioniiues surrounding the eduction-flues and heatedthereby and having separate groups of discharge-orifices arranged inproximity with said gas-outlets, and means at the points ot' admissionfor controlling the intake of air to each system ot' induction-linesthereby providing independent secondary air-supplies for dierentportions of the setting throughout its length, substantially asdescribed.

In testimony whereof we have hereunto signed our names.
